Fresh water price index based on water quality

ABSTRACT

A method and system for computing a stable index value of fresh water based on water quality category and/or grade from current values of root commodities (i.e. freely marketed products) that either have fresh water as a constituent and/or utilize fresh water in their production, usable to develop a stable investment instrument for investing in fresh water. A processor may process associations between a root commodity and a water quality category of fresh water. A display associated with a computer may display updateable current prices of fresh water of a particular water quality category and/or grade and updateable current prices of one or more root commodities. A water measurement device may measure at least one water source of fresh water with respect to at least one of TDS, carbonate content, pH, hardness, sodium, chloride, nitrate, toxins and sodium adsorption ratio and compare against standards to categorize the fresh water.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to systems and methods for making a stableprice of fresh water and financial instruments using such price and moreparticularly, to systems and methods where the price or index value offresh water is based on the water quality.

Fresh water is an essential and irreplaceable commodity that is becomingscarcer. Fresh water is also a very desirable commodity for investment.Investment money is needed for protecting, purifying and distributingwater. On the other hand, the market for water is strongly affected bylocal and temporal factors and prices vary wildly. In order to investsafely in water an investor needs additional protection.

It is important that the water market take into account water quality.This is true from rational economic point of view of investors—the truevalue of water strongly depends on the water quality. It is also truefrom a more idealistic conversationalist point of view because in orderto increase the incentive to protect water quality, it is necessary thatthe value of water for holders reflects its quality.

A few factors make developing a rational price index for water differentfrom and more difficult than other commodities. First, water is a highlyregulated commodity and its price often does not reflect its true marketvalue. Secondly, water is an essential element in a vast number ofdifferent processes. Different aspects of water quality of differingeffect on its value for the different uses.

Concerning the first difficulty, it has already been pointed out in U.S.Pat. No. 8,024,239 to Inventor Shirazi (Title: Aqua Index) issued Sep.20, 2011 (hereinafter “Shirazi '239 patent”), which patent is herebyincorporated by reference in its entirety, that the political andeconomic importance of water limits the potential of trade as a policytool to mitigate water scarcity. National and local governments use exittees, fixed taxing and progressive taxing of water on one hand, andsubsidization of water on the other hand to protect local water suppliesor encourage water intensive industries (like agriculture). Water has awide range of prices (e.g. 0.16-4.00 usd/m3) and exit fees (e.g. 0-70%in different provinces in Australia), and tax rates (e.g. 10-50%progressive tax and 30% subsidization for agriculture in Israel). As aresult, no one has been able to build a stable international market forwater.

Concerning the second problem, it has been pointed out by the TennesseeWater Control Board (see Rules of Tennessee Dept. of Environment andConservation Division of Water Pollution Control, Chapter 1200-4-1,http://tn.gov/sos/rules/1200/1200-04/1200-04-01.pdf) that water has manyuses, which in the public interest are reasonable and necessary. Suchuses include sources of water supply for domestic and industrialpurposes; propagation and maintenance of fish and other aquatic life;recreation in and on the waters including the safe consumption of fishand shellfish; livestock watering and irrigation; navigation; generationof power; propagation and maintenance of wildlife; and the enjoyment ofscenic and aesthetic qualities of waters. The rigid application ofuniform water quality is not desirable or reasonable because of thevarying uses of such waters.

Therefore, to develop a unified price index for water as a commodityrequires consideration of aspects of use and interaction of qualityfactors and uses in a way that is different from any other commodity.

One cannot just define certain “good” and “bad” aspects of water qualityand assign points (like is done in other commodities). This is stateddearly for example by the FAO (Food and Agriculture organization of theUnited Nations):

Conceptually, water quality refers to the characteristics of a watersupply that will influence its suitability for a specific use, i.e. howwell the quality meets the needs of the user. Quality is defined bycertain physical, chemical and biological characteristics. Even apersonal preference such as taste is a simple evaluation ofacceptability. For example, if two drinking waters of equally goodquality are available, people may express a preference for one supplyrather than the other; the better tasting water becomes the preferredsupply. In irrigation water evaluation, emphasis is placed on thechemical and physical characteristics of the water and only rarely areany other factors considered important.

Specific uses have different quality needs and one water supply isconsidered more acceptable (of better quality) if it produces betterresults or causes fewer problems than an alternative water supply. Forexample, good quality river water which can be used successfully forirrigation may, because of its sediment load, be unacceptable formunicipal use without treatment to remove the sediment. Similarly,snowmelt water of excellent quality for municipal use may be toocorrosive for industrial use without treatment to reduce its corrosionpotential. Obviously one cannot just define uses of water and make thevalue a weighted average of the value for each use since this wouldpenalize a water that is fit for drinking if it was also fit foragriculture. In reality, due to the vast difference in quantitativedemand, it is sometimes advantageous to sell drinking quality water toagriculture.

There is therefore a compelling need to have a stable price for freshwater that is based on water quality and to have financial instrumentsbased on such a price.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplatedmodes of carrying out the invention. The description is not to be takenin a limiting sense, but is made merely for the purpose of illustratingthe general principles of the invention, since the scope of theinvention is best defined by the appended claims.

The present invention generally provides a method and system forcreating a stable price of fresh water that is based on the quality ofthe fresh water. This may be applied to fresh water of a particularwater source. A financial instrument identifying on its face aparticular amount of fresh water of a particular water quality categorymay state a price determined using an index value of fresh water of aparticular water quality category. The method of the present inventionmay include determining, using a computer processor, current prices ofat least one root commodity, each root commodity being other than water,each root commodity of the at least one root commodity having at leastone of (i) water as a constituent in said each root commodity and (ii)water utilized in production of said each root commodity. The method mayalso include associating or matching each of at least one water qualitycategory and/or quality grade with at least one root commodity such thata quality of water either constituent in the root commodity or used inproduction of the root commodity meets water quality standards of therespective water quality category.

The method may also involve determining, using a computer processor, acurrent index value for fresh water for each water quality category ofthe at least one water quality category. The method may also includemeasuring fresh water of at least one water source with respect tochemical or physical criteria such as at least one of TDS, carbonatecontent, pH, hardness, sodium, chloride, nitrate, toxins and sodiumabsorption ratio to determine the water quality category and/or thewater quality grade of fresh water from that water source. A system ofthe present invention may include a water quality measuring device formeasuring fresh water of at least one water source with respect to atleast one of TDS, carbonate content, pH, hardness, sodium, chloride,nitrate, toxins and sodium absorption ratio. The system may also includea computer for receiving data from the water quality measuring devicewith respect to the fresh water in regard to the at least one of TDS,carbonate content, pH, hardness, sodium, chloride, nitrate, toxins andsodium absorption ratio and for comparing the received data to storedwater quality standards to determine a water quality category for thefresh water. The computer may also determine current prices of at leastone root commodity (the root commodities being other than water), eachroot commodity of the at least one root commodity having at least one of(i) water as a constituent in the root commodity and (ii) water utilizedin production of the root commodity. The computer may also be forprocessing associations between each of at least one water qualitycategory with at least one root commodity and determining a currentindex value for fresh water of each of the water quality categoriesbased on a current price of said each root commodity and based on atleast one of (i) a quantity of fresh water constituent in the rootcommodity associated with said each water quality category and (ii) aquantity of fresh water used in production of the root commodity. Thepresent invention may also include in the method or system a displayassociated with a computer displaying an updateable current price of oneor more root commodities and an updateable current price of fresh waterof a particular (i) water quality category, (ii) water quality grade or(iii) water quality category and water quality grade, the current priceof the fresh water of the particular water quality being dependent onthe current price of the one or more root commodities. The independentvariable (prices of root commodities) may be displayed on a differentportion of the display that the dependent variable (prices of the freshwater of a particular water quality category and/or grade.

In contrast to the prior art, where there is neither a method nor asystem for creating a stable price for fresh water other than U.S. Pat.No. 8,024,239, and where in that '239 patent the price does not takeinto consideration water quality, the method and system of the presentinvention may create a stable price for fresh water, and a financialinstrument associated therewith, which takes into consideration thequality of the water. By considering the quality of the water, the pricemay be more accurate, more stable and more tailored to the differentwater sources throughout the different regions of the world. In fact,today certain bottled water that comes from the Swiss Alps may commandan inflated price, i.e. a higher price than the quality would dictate,from the fact that the Alps have a reputation for high quality water yetin reality, due to constant pollution from pharmaceutical companies inthe area, the quality has suffered. The present invention would lead toa more accurate, quality-based price since the price may be tied to thewater quality and since the quality of that water source may be measuredand this measurement may be updated at reasonable intervals, for exampleannually. Furthermore, having the price of water be based on waterquality may better enable the utilization of water resources asfinancial collateral. This may further facilitate trade at a time whennew equity is desperately being sought, particularly in Europe. Incontrast to the prior art, where the price of the water may not be basedon water quality categories, the present invention, by utilizingcategories of water quality to create a price and to create financialinstruments using that price, may encourage better water quality sinceone may be able to charge a higher price for water of higher waterquality. In further contrast to the prior art, the present invention mayadjust a price of water based on geographical location of the watersource. In contrast to the prior art, in which a display may displayonly one type of commodity, the display used in the method and system ofthe present invention may display both prices (or an index of) one ormore root commodities and a price (or an index) for one or morecategories and/or grade of fresh water based on quality, wherein theprice of the fresh water may be derived from the price of one or more ofthe root commodities. Furthermore, in further contrast to the prior art,in which a display of commodity prices may have various prices ofvarious commodities in a particular portion of the display, but wherethere is no dependence between the price of one commodity displayed andthe price of another commodity displayed, the display associated withthe system and method of the present invention may display prices of oneor more root commodities and prices or indices of one or more waterquality categories and/or one or more water quality grades of freshwater wherein the price of the water is derived from tire price of oneor more of the root commodities. Furthermore, in certain preferredembodiments, the display of the method and system of the presentinvention may include a display of prices of one or more rootcommodities in a first portion of the display and the prices of variousquality categories and/quality grades of fresh water in a second portionof the display, wherein the prices of the one or more quality categoriesand/or grades of fresh water displayed in the second portion of thedisplay may be derived from and dependent on the displayed prices of oneor more of the root commodities displayed in the first portion of thedisplay. Each of these displayed prices may be constantly updated. Bydisplaying the price of a water commodity and the price of rootcommodities from which the price of water commodity is computed in thismanner, a user of the display may be presented with a graphicalillustration, discernable at a glance, of the relationship of the priceof water to the price of the root commodities. This may provide users ofthe display with a better appreciation of this relationship between thecommodities. Furthermore, by displaying water indices separately fromother commodities, this may draw attention to tire new use of water as acommodity and encourage water quality improvement since the prices ofthe water are tied to the quality category and/or grade of the freshwater. In further contrast to the prior art, in which water is measuredmerely to see if it meets minimal standards for drinking, the presentinvention may include a step of measuring the quality of a source ofwater (for example for TDS, carbonate, pH etc.) in order to fit thewater into water quality categories (i.e. for pristine, for domestic,agricultural, industrial) and optionally grades of quality within eachcategory. Furthermore, in contrast to the prior art, the presentinvention may include a step of measure the quality of the water sourcein order to create categories of water quality to create separate prices(base prices or otherwise) for each water quality category.

The principles and operation of a method and system for a fresh waterprice index based on water quality according to the present inventionmay be better understood with reference to the drawings and theaccompanying description.

Following are some examples of how to calculate a price of fresh water(and a financial instrument based on such a price) that is based onwater quality.

“Fresh water” should be understood as including fresh water that hassolidified in the form of ice, for example icebergs. When referring inthis patent application to “associating”, “association” or “matching”water quality categories with root commodities, this should beunderstood as also encompassing associating or matching root commoditieswith only a portion of a water quality category (i.e. a grade). Forexample, a matching of grade A1 (where “A” is the water qualitycategory) with a root commodity, shall be understood to fall within andbe an example of matching or associating water quality categories withroot commodities.

In order to define a stable market for water based on water quality, onemay define a few basic water quality categories. Then making use of U.S.Pat. No. 8,024,239 to Shirazi, one may define a market value for waterfor each water quality category or water category use based on the priceof freely traded commodities that require water of the each givenquality type. Then one may define a price index for different qualitiesof water based on the applicable use and price. Finally, one may computea price of water from a particular water source based on the suitabilityof the water for the different categories of water quality or use.

Categories—four general categories of water use are:

-   -   1. Pristine quality—fit to sell and drink untreated as mineral        or spring water; 1a Drinking water derived from icebergs,        treated or untreated    -   2. Domestic—high quality—fit to optionally treat (e.g. add        chlorine, fluoride or other supplements), to sell, and        distribute for drinking or other residential-type purposes (i.e.        showers) that is typically run through a water faucet rather        than placed into bottles for sale;    -   3. Agricultural quality—medium quality;    -   4. Industrial quality minimum quality, will not harm machines or        manufacturing process.

Water quality may be characterized according to the following aspects:

-   -   1. Total Dissolved Solids (TDS)    -   2. Carbonate Content (H₂CO₃)    -   3. pH    -   4. Hardness (Ca, Mg)—expressed as mg/l CaCO₃    -   5. Sodium (Na)    -   6. Chloride (Cl)    -   7. Nitrate (NO₃)    -   8. Toxins    -   9. Sodium Adsorption Ratio (SAR)

Specific Requirements

Pristine Water

In order to be salable as spring or mineral water, water has to comefrom a natural source that is drinkable without treatment. In generalthis entails that the water fulfill drinking standards and be protectedfrom contact with human diseases. Practically this applies only topristine ground water (deep groundwater or groundwater from anuninhabited area) which also fulfill drinking water standards.

To qualify as pristine, water must come either from a deep confinedaquifer or from a protected area (e.g. uninhabited area).

Toxins must be within drinking water standards. It is not the intentionherein to list all toxins in water since this is known in the standardand since standards may change over time as to what constitutes a toxin.Rather, what is presented below is an example of how criteria may bedeveloped from available knowledge to produce a systematic quality basedvalue system for water. An example of drinking water standards fortoxins

TABLE 1 Quality requirements for pristine water (Medium quality) TDS<3,500 mg/l H₂CO₃ <1500 mg/l pH 5-10 CaCO₃ 500 mg/l Na <20 mg/l Cl <300mg/l NO₃ <5 mg/lIn some preferred embodiments, there may be a further categorization ofpristine water into grades. For example, bottled water (which is anexample of water from pristine source) may be broken down into gradesand labeled/graded for example as A_(bottled)1, A_(bottled)2,A_(bottled)3 based on whether relative quality of the bottled water ishigh, medium or low.

Total Dissolved Solids (TDS)

Regulations regarding TDS vary throughout the world. In the UnitedStates, for example, bottled water must contain at least 250 mg/l TDS tobe labeled as mineral water. TDS above 500 mg/l qualifies water as “lowmineral content”; more than 1,500 mg/l allows a “high mineral content”label.

Distilled water has a TDS of 0 mg/l; seawater has about 34,000 mg/l.Most bottled waters fall within a TDS range of 50 to 800 mg/l (Ducale,55 mg/l; Parana, 188 mg/l; Fiji, 210 mg/l; Evian, 357 mg/l; Perrier, 475mg/l), but many highly regarded waters have a much higher TDS (SanPellegrino, 1,109 mg/l; Badoit, 1,200 mg/l; Contrex, 2,032 mg/l;Gerolsteiner, 2,527 mg/l). Some of these waters are thought to becuratives-their mineral compositions are believed to have healingproperties (Famous Crazy, 2,783 mg/l; Vichy Célestins, 3,378 mg/l). Butsome curative waters have a low TDS: Fiuggi, for example, has a TDS ofonly 122 mg/l.

Hardness

Hard water does not negatively affect health or taste. According to theU.S.

National Research Council, the magnesium and calcium in hard water canactually contribute to daily dietary requirements.

pH

pH has a very minor effect on the taste of water and no known healtheffects.

Domestic

Water that meets drinking quality standards, but does not come from aprotected source is not recommended for drinking without treatment(although there are bottlers that sell such water without treatment, thepractice is frowned upon and has led to disease outbreaks). Under anyconditions, while certain brands of “spring water” from suburban wellsmay fetch a high price, this is not a function of the quality of thewater.

Generally, along with meeting health and taste standards, domestic watermust also be fit for general use and transport. This puts limits ondomestic quality water that are not found in more expensive pristinewaters. For example,

-   -   the pH of domestic water must not be too low (in order to        prevent corrosion and leaching of pipes);    -   domestic water should not be too hard (Ca, Mg); hard water makes        cleaning more difficult and more dependent on soaps and        synthetic detergents; hardness also causes scaling in boilers;        softening water adds Na and can have negative effects on the        taste of water;    -   drinking water standards do not allow high TDS in domestic water        (as opposed to prestigious mineral waters).

TABLE 2 Quality requirement for domestic water High quality mediumquality low quality TDS <50 mg/l <150 mg/l <500 mg/l H₂CO₃ 30 < H₂CO₃ <250 mg/l <400 mg/l <500 mg/l pH 5-10 5-10 mg/l 5-10 mg/l CaCO₃ <100 mg/l<200 mg/l <400 mg/l Na <5 mg/l <20 mg/l <50 mg/l Cl <20 mg/l <300 mg/l<400 mg/l NO₃ <1 mg/l <5 mg/l <20 mg/lToxins must be less than drinking water standards

Agricultural

A very important factor in the suitability of water for irrigation isthe salt content. The suitability of a water for irrigation isdetermined not only by the total amount of salt present (measured asTDS) but also by the kind of salt. The problems caused by salts varyboth in kind and degree, and are modified by soil, climate and crop, aswell as by the skill and knowledge of the water user. As a result, thereis no set limit on water quality; rather, its suitability for use isdetermined by the conditions of use which affect the accumulation of thewater constituents and which may restrict crop yield. The soil problemsmost commonly encountered and used as a basis to evaluate water qualityare those related to salinity, water infiltration rate, toxicity and agroup of other miscellaneous problems.

Salinity—Salts in soil or water reduce water availability to the crop tosuch an extent that yield is affected.

Water Infiltration Rate—Relatively high sodium or low calcium content ofsoil or water reduces the rate at which irrigation water enters soil tosuch an extent that sufficient water cannot infiltrate to supply thecrop adequately from one irrigation to the next.

Specific Ion Toxicity—Certain ions (sodium, chloride, or boron) fromsoil or water accumulate in a sensitive crop to concentrations highenough to cause crop damage and reduce yields.

Miscellaneous—Excessive nutrients reduce yield or quality; unsightlydeposits on fruit or foliage reduce marketability; excessive corrosionof equipment increases maintenance and repairs.

An important factor in the suitability of water for agriculture which isnot present in drinking water standards is the SAR (Sodium AdsorptionRatio) defined as Na/((Ca+Mg)/2)^(1/2) where Na, Ca, and Mg are theequivalent concentrations of the respective ions in me/l. According tothe FAO the ability of water to infiltrate is controlled by the SAR andthe TDS approximately as follows.

TABLE 3 SAR requirements for agricultural water High quality Mediumquality Low quality 0-3 and TDS =  >500 mg/l 500-75 mg/l <75 mg/l 3-6= >1000 mg/l 1000-150 mg/l <150 mg/l 6-12 = >1500 mg/l 1500-400 mg/l<400 mg/l 12-20 = >2000 mg/l 2000-1500 mg/l <1500 mg/l 20-40 = >5000mg/l 5000-2000 mg/l <2000 mg/l

Similar to toxins for drinking water, one may define water as fit foragriculture only if certain plant toxins are within the limitationslisted in table 2 of the attached FAO document Water Quality forAgriculturehttp://www.fao.org/docrep/003/T0234E/T0234E01.htm#ch1.2.industrial

One may assume that industrial use has certain minimal requirements tothe effect that the water not damage machinery.

Quality Categories—an Index Pricing

Based on an analysis of relevant aspects of water quality we can designa unified basis for pricing. For example, the price structure maycategorize water by its most strict use. Then the various qualityaspects may be used to determine quality categories within each primaryuse category.

Water Categories

Water may be categorized into the following four general categories ofuse:

-   -   A. Domestic at least fulfills minimal domestic standards;    -   B. Agricultural—does not meet drinking standards by at least        fulfills minimal agricultural standards;    -   C. Industrial quality—does not fit agricultural or drinking        standards, but fulfills at least minimal industrial standards.

Categories of Water Quality

Pristine Water

Pristine water is water from a pristine natural source that is drinkablewithout treatment. To qualify as pristine, water must come either fromdeep confined aquifer or from a protected area (e.g. uninhabited area).Toxins must be within drinking water standards. For example, to qualifyas “pristine” waters, water will need to fulfill the minimal drinkingwater standards of some large body e.g. the US, the EEC or WHO for toxincontent. In some cases, standards for pristine ready-to-drink water maydiffer from (and even be less strict than) municipal water standards.

Pristine water must come from a protected source, and fulfill therequirements of Table 1, and be within EEC drinking standards except forwhere they differ from Table 1.

Due to the limited marketability of bottled water, pristine water, thevalue of pristine water depends on its secondary use. Pristine water ofmunicipal quality (A1, A2, A3) may be assigned a value of ⅓ the value ofpurified water+⅔ the value of domestic water. Pristine water not ofmunicipal quality (B1, B2, B3, C1, C2, C3) may be assigned a value of ¼the value of bottled water+¾ the value of water for secondary use.(Since pristine water is to be used for drinking, pristine water loses alot of value if it does not fit drinking standards). It should beunderstood that these assigned fractions (⅓ and ⅔; ¼ and ¾) are merelyexamples of fractions that may be chosen to effectuate weightedcombinations and other fractional amounts (or non-fractionalcoefficients) may be used.

For example, the value of purified water (used to calculate the value ofpristine water) may be calculated from the prices of ready-to-drinkwaters (bottled water and purified water). An example of suchcalculation is given in U.S. Pat. No. 8,024,239; there, the value ofpurified water is labeled Pb and may sometimes be referred to as“bottled water”. Herein the terms “bottled water” and Pb may also beused in the more general sense of “ready to drink waters”.

In an alternative arrangement, pristine water may also receive a secondf* bonus/penalty due to its secondary use. If the A1 water ALSO fulfillsA2 standards then f*=1.2. If the A2 water does not fulfill A2 standardsbut fulfills A3 standards then f*=1. If the A1 water docs not fulfill A3standards but fulfills B3 standards then f*=0.5. If the A2 water doesnot fulfill A3 standards or B1 standards then f*=0.3.

A1, A2, A3: Domestic

Water that meets drinking quality standards, but does not necessarilycome from a protected source is not recommended for drinking withouttreatment.

A1 water must fulfill the requirements of high quality drinking waterfrom Table 2, and be within EEC drinking standards except for where theydiffer from the requirements of high quality drinking water from Table2.

A2 water must fulfill the requirements of medium quality drinking waterfrom Table 2, and be within EEC drinking standards except for where theydiffer from the requirements of medium quality drinking water from Table2.

A3 water must fulfill the requirements of low quality drinking waterfrom Table 2, and be within EEC drinking standards except for where theydiffer from the requirements of low quality drinking water from Table 2.

B1, B2, B3: Agricultural

Category B is for water that is not pristine and not fit for drinking(domestic) use, but is fit for agricultural use.

B1—fulfills the medium quality standards of Table 3 and the high qualitystandards of Table 4.

B2—fulfills all of medium quality standards of Table 3 and Table 4.

B3—fulfills all of low quality standards of Table 3 and Table 4.

Similar to toxins for drinking water, one may define water as fit foragriculture only if certain plant toxins are within the limitationslisted in table 2 of the attached FAO document Water Quality forAgriculture http://www.fao.org/docrep/003/T0234E/T0234E01.htm#ch1.2,incorporated herein by reference.

Alternatively, agricultural waters may be graded according tosuitability to a given crop. For example, waters suitable for all cropsmay be defined as B1 whereas water suitable for grain and trees but notfor vegetables may be B2 and water suitable for trees only may be B3.

C1, C2, C3: Industrial

Category C is for water that is not pristine and not fit for drinking(domestic) use, and is not fit for agricultural use, but is fit orindustrial use. Subcategories of category C may be created. For example,

C1—fulfills all of high quality standards of Table 5.C2—fulfills all of medium quality standards of Table 5.C3—fulfills all of low quality standards of Table 5.

Pricing

From the above, various possible pricing systems can be made. Forexample:

From U.S. Pat. No. 8,024,239 to Shirazi the prices of water according touse are:

TOTAL Fresh Expe domestic desalinate bottled purify food crops biofuels$0.89 Portion 0.05 0.5 0.0995 0.0005 0.05 0.2 0.1 Value $0.92 $0.77$2.11 $200.00 $1.75 $0.20 $0.22 W*X 0.046 0.38375 0.209945 0.1 0.08750.0396 0.022 bottled = bottled + purify: portion = Wb = 0.05 + 0.0005 =0.0505; price = Pb = (.05($1.75) + 0.0005($200))/0.0505 = $3.71 domestic= domestic + export + desalinate; portion = Wd = 0.05 + 0.5 + .0995 =0.65; price = Pd = (.05($0.92) + 0.5($0.77) + 0.0995($2.11))/0.65 =$0.99 agriculture = food crops portion = Wa = 0.2; price = Pa = $0.040industrial = biofuels portion = Wi = 0.1; price = Pi = $0.022

In the above Table 6, “Portion (W)” may be described as the market shareof that category of water in the total fresh water market.

We will take the base water price of agricultural water as Pa=$0.04.Then the price will be adjusted as follows. The three rows of Table 7abelow represent different levels of suitability relative to certainwater quality standards of water that comes from a particular source, orspecific water being sold:

Pristine water of municipal quality (A1, A2, A3) has been assumed inthese calculations to have a value of ⅓ the value of purified water+⅔the value of domestic water. It should be understood that these assignedfractions (⅓ and ⅔; ¼ and ¾) are merely examples of fractions that maybe chosen to effectuate weighted combinations and other fractionalamounts (or non-fractional coefficients) may be used.

Pristine water not of municipal quality (B1, B2, B3, C1, C2, C3) hasbeen assumed in these calculations to have a value of ¼ the value ofpurified water+¾ secondary use. The selection of the fraction may differand this is only an example of how to mathematically represent aweighted combination.

The calculated price will be the price factor times the base price(Pa=$0.04). Thus, the resulting index prices are in dollars per m³ basedon the Shirazi U.S. Pat. No. 8,024,239 data:

The water price index may take into account geographical preferences(i.e. pristine A1 water from Iceland may be more valuable that pristineA1 water from Brazil).

Packaging infrastructure, distance from markets and transportationroutes may also have to be taken into account when formulating a finalprice for the fresh water. Transportation and storage costs may be asignificant part of the overall price of a final price that a buyerpays. The price of fresh water displayed in a commodities exchange orwhich is used for a financial instrument may include the storage andtransport costs or in other case do not include such costs. Examples ofpackaging include shipping containers, large plastic bags holding thefresh water and in situ (at the source of the water) storage.Optionally, the market for natural gas may be considered as a model forthese storage and transportation factors since, like water, a large partof the price of natural gas is for transport.

Examples

Based on the above water a good municipal water supply would (forexample) have an A2 rating.

Ulvato bottled water is grade A1 (pristine) but does not fit domesticwater standards (to high TDS) or agricultural standards (to low pH)therefore f*=0.3 and would be evaluated as 0.3*1.88=$0.57/m³

Ulvato water: 752 TDS 5.8 ph factor 796 Hardness 171 Calcium 79 Chloride1 Fluoride 574 Hydrogeniccarbonate 28 Magnesium 6.9 Nitrate 8 Potassium11 Silica 74 Sodium 104 Sulphates

Santa Vittoria water is pristine and gets A1 rating. It is also does notmeet A2 high quality domestic water standards (too high TDS carbonatesand nitrate) but does fulfill A3 standards therefore f*=1 and the indexprice is $1.88/m³.

Santa Vittoria Analysis: Temp. at source: 47° F. (8.3° C.) 169 TDS 8 phfactor 36.2 Calcium 0.9 Chloride 189.0 Hydrogen carbonate 18.4 Magnesium2.5 Nitrate 0.5 Potassium 0.6 Sodium

Lake Placid N.Y. tor example would get an A2 rating, and therefore anindex price of $0.90/m³.

Pricing—Another Possible System

Other possible pricing systems can be made. For example:

Starting with the index prices of U.S. Pat. No. 8,024,239 to Shirazi(Table 6) another way of computing a price would be to add a suitabilityfactor (f) to the price equation of U.S. Pat. No. 8,024,239 to Shirazi.P=Fb*Pb*Wb+Fd*Pd*Wdb+Fa*Pa*Wa+Fi*Pi*Wi

For example: For a given water and use:

-   -   f=1.0 if the water is high quality for that use    -   f=0.8 if the water is medium quality for that use    -   f=0.5 if the water is high low for that use    -   f=0.25 if the water is not fit for that use

Thus, the price of water fit for being bottled Fb=1.0, highly fit fordomestic Fd=1.0, well fit for agriculture Fa=1.0 and well fit forindustry Fi=1.0 may be computed as the following combination ofelements:

1.0*0.05*3.71+1.0*0.65*0.99+1.0*0.2*0.4+1.0*0.1*0.022=0.83

In another example, the price of water not fit for bottled Fb=0.25,having medium fitness for domestic Fd=0.8, well fit for agricultureFa=1.0 and well fit for industry Fi=1.0 may be computed by combining asfollows:

0.25*0.05*3.71+0.8*0.65*0.99+1.0*0.2*0.4+1.0*0.1*0.022=0.57

In a third example, the price of water fit for being bottled Fb=1.0, lowfit for domestic Fd=0.5, low fit for agriculture Fa=0.5 and well fit forindustry Fi=1.0 may be calculated as

1.0*0.05*3.71+0.5*0.65*0.99+0.5*0.2*0.4+1.0*0.1*0.022=0.57.

In each of the above three examples, each of the four addends comprisethree multiplicands including (1) the suitability factor of the waterfor a respective water quality category, (2) a market share of the waterquality category and (3) a price index for water of that water qualitycategory.

Accordingly, as shown in FIG. 1, the present invention may in general becharacterized as a method 100 for investing in fresh water based on aquality of the fresh water. Method 100 may have a step 110 of (a)determining, using a computer processor, current prices of at least oneroot commodity other than water (all root commodities being other thanwater), each root commodity of the at least one root commodity having atleast one of (i) water as a constituent in said each root commodity and(ii) water utilized in production of said each root commodity.

Another step 120 of method 100 may be associating or matching each of atleast one water quality category in a plurality of water qualitycategories with at least one root commodity of the plurality of rootcommodities. The matching or associating may be such that a quality ofwater (i) that is used in production of the root commodity and/or (ii)that is constituent in the root commodity, meets (or in other preferredembodiments is related to) water quality standards of the respectivewater quality category. An example of matching/associating is to takecorn as a root commodity and match or associate either the waterconstituent in corn and/or the water used in the production of corn,with water quality category B1, B2 or B3 (water that is suitable foragricultural use and fits certain standards of Tables 3 and 4). One maymake the assumption, for example, that water in corn and/or water usedin the production of corn meets (or in other preferred embodiments isotherwise related to) the water quality standards B1 or B2 or B3. Step120 may in some preferred embodiments be performed by a processor.

Alternative versions of step 120 (or equivalent steps/elements of othermethods/systems) may be possible. That is, one may associate or matcheach of at least one water quality category in at least one waterquality categories with at least one root commodity such that a qualityof water (i) that is used in production of the root commodity and/or(ii) that is constituent in the root commodity, is related to waterquality standards of the respective water quality category in some otherway. To take one example, instead of meeting the standard, the watermeets part of the standard or meets the lowest acceptable example of thestandard or is within 50% (or another percentage) of the standard. Inany method or system of the present invention, instead of a waterquality category, the association may be made between a water qualitygrade (i.e. “A1”) within the broader water quality category and the atleast one root commodity.

A further step 130 of method 100 may be determining, using a computerprocessor, for each water quality category of the at least one waterquality category, a current index value for fresh water meeting saideach water quality category, the index value determined based on acurrent price of said each root commodity that was matched with saideach water quality category and based on at least one of (i) a quantityof fresh water constituent in said each root commodity that was matchedwith said each water quality category and (ii) a quantity of fresh waterused in production of said each root commodity that was matched withsaid each water quality category.

Method 100 may also include physically measuring fresh water of at leastone water source with respect to chemical or physical criteria of thewater, for example measuring at least one of TDS, carbonate content, pH,hardness, sodium, chloride, nitrate, toxins and sodium adsorption ratio,to determine the water quality category and/or the water quality gradeof fresh water from that water source. The results of the measuring maybe compared to pre-set water quality standards in the form of ranges ofeach item (e.g. TDS, carbonate content, pH, hardness, sodium, chloride,nitrate, toxins and sodium adsorption ratio) associated with each waterquality category and/or water quality grade, as set forth in Tables 1through 5 above and in the suggested definitions of water quality gradesA1, A2, A3, B1, B2, B3, C1, C2, C3 discussed above. The water qualitymeasuring may be performed using one or more water quality measuringdevices 380, 680, 780 (see FIGS. 6A, 6B, 7, 8). Updates of the waterquality of a water source may be performed by re-measuring the watersource using a water measuring device at a reasonable interval.Typically, water sources may be re-measured and updated as to qualitycategories and grades annually or in some cases more frequently or lessfrequently.

Method 100 (or method 200 or method 800) may have a further stepinvolving a display. In some preferred embodiments, such as shown inFIG. 5B, the further step may comprise displaying on a display 330associated with a computer an updateable current price of one or moreroot commodities and an updateable current price of fresh water of aparticular (i) water quality category, (ii) water quality grade or (iii)water quality category and water quality grade, wherein the currentprice of the fresh water of the particular water quality is dependent onthe current price of the one or more root commodities. The arrow in FIG.5B indicates that the displayed prices and indicia are moving like a“ticker tape”.

A numerically significant change in the current price of the one or moreroot commodities (which may be viewed as an independent variable) mayresult in a visible change in the current price of the fresh water ofthe particular water quality (which may be viewed as a dependentvariable). A “numerically significant” change in the price of theindependent variable may be defined as a change that is enough to bringabout a change of at least one digit of the displayed price of thedependent variable.

In other preferred embodiments, as shown in FIG. 5A, the further stepinvolving the display may comprise displaying on a first portion of adisplay associated with a computer (which may be the computer processorused in step 120) at least one of the current index values for freshwater (which may be updateable) and some name or indicia (i.e. “waterB3”) identifying water as the commodity and/or the category and/or gradeof fresh water whose current index value is displayed on the firstportion. In any method or system of the present invention, an indiciamay identify a category of fresh water by denoting water of thatcategory even without including the term “water” or the term “H₂O” aspart of the indicia such as by using some other symbol known to thosewho may view the display as indicating water or water of a particularquality category and/or grade. The display may also display on a secondportion of the display a current price of at least one root commodityfrom which the at least one of the current index values is derived andsome name or indicia (i.e. “corn”) identifying a root commodity (andpreferably each such root commodity) whose current price is displayed onthe second portion. Accordingly, an independent variable being a currentprice of at least one root commodity may be displayed on one portion ofthe display and a dependent variable being a current price of at leastone water quality category and/or grade may be displayed on a differentportion of the display. This may cause the prices of the fresh water(and its quality) and its dependence on the root commodity prices to bemore conspicuous.

It should be understood that the displays of FIGS. 5A and 5B are merelyexamples of how the prices/indices may be displayed. Furthermore, inFIG. 5A, the first and second portions 331, 332 of the display 330 areshown one on top of the other and as a moving “tape”. This is of coursenot a limitation and the first and second portion can be in a statictable format or in any other visible format.

In any method or system of the present invention, the current indexvalues or the at least one of the current index values displayed may beupdated over time as the factors used in determining the pricethemselves get updated. For example, the displayed current price of theone or more root commodities may vary and be updated. In addition, ifthere are multiple root commodities, the market share of the variousrespective root commodities may change. In addition, the amount of waterconstituent in the root commodities may change and the amount of waterused in production of a root commodity may change, although these lattertwo factors are not as likely to change as often as the market share orprice. With respect to any of the methods or systems of the presentinvention, the display and in particular the prices and index values onthe display, may be accessible to the public either by appearing on aweb site or on a ticker tape on a building or in other ways known in theart for the display of commodity prices.

In some preferred embodiments, a further step of the method 100 may bedetermining, using a processor, a price of fresh water derived from aparticular water source (or a specific amount of water being sold) bydetermining a current level of suitability of that fresh water for eachof the plurality of water quality categories and by then combining allof the current index values of the fresh water of each water qualitycategories together by weighting each index value being combined by (i)the determined current level of suitability of the fresh water beingpriced (i.e. water from the particular water source or the specificquantity of water being sold) for each of the plurality of water qualitycategories and by (ii) a market share of water from each water qualitycategory.

An example of use of the level of suitability is provided above using asuitability factor (f).

As shown in FIG. 2, another method 200 of the present invention issimilar to method 100 except that the matching or associating step 220may be performed such that a quality of water that is constituent in therespective root commodity meets (or in other preferred embodiments isotherwise related to) water quality standards of the respective waterquality category. It should be understood that in any method (or system)of the present invention, there is no limit to the number of rootcommodities that are used to derive the current price of the fresh waterof a particular quality category and/or grade.

As shown in FIG. 3, the present invention may be described as a method800 of using financial instruments to invest in fresh water based ofwater quality. Method 800 may have a step 810 of determining, using acomputer processor, a price of each of the financial instrumentsidentifying on its face a particular amount of fresh water of aparticular water quality category, the price of each financialinstrument determined using an index value of fresh water of aparticular water quality category. Step 820 may be having a computerstore water quality standards for a plurality of water qualitycategories. Method 800 may have additional steps that are similar tomethods 100 or 200 or 400 (or in other embodiments to the stepsperformed by the computer in systems 300 or 600). For example, method800 may have a step 830 of determining, using a computer processor,current prices of at least one root commodity, the root commoditiesbeing other than water, each root commodity in the at least one rootcommodity having at least one of (i) water as a constituent in said eachroot commodity and (ii) water utilized in production of said each rootcommodity. Step 840 may be associating each water quality category ofthe at least one water quality category with a root commodity of theleast one root commodity. The associating or matching may be such that aquality of water either (i) constituent in a respective root commodityand/or (ii) used in production of the respective root commodity, meets(or in other embodiments is related to) water quality standards of therespective water quality category. Step 850 may be determining, using acomputer processor, for each water quality category of the at least onewater quality category, the index value for fresh water meeting saideach water quality category, the index value determined based on acurrent price of said each root commodity associated with said eachwater quality category and based on at least one of (i) a quantity offresh water constituent in said each root commodity associated with saideach water quality category and (ii) a quantity of fresh water used inproduction of said each root commodity associated with said each waterquality category.

Method 800 may, in some preferred embodiments, have a step of displayingon a first portion of a display (such as the display 330 shown in FIG.5A) associated with a computer processor at least one of the indexvalues for fresh water, the display also displaying on a second portionof the display (or in some embodiments also on the first portion of thedisplay) a price of at least one root commodity from which the at leastone of the index values is derived, the at least one of the index valuesand the price of the at least one root commodity each being updated overtime. In some preferred embodiments, a user looking at display 330 coulddiscern changes in a price index of at least one root commodity followedby changes in a price index of at least one water quality category orgrade within such water quality category such that the changes in theprice index of the at least one water quality category may appear to berelated to changes in the price index of the at least one rootcommodity.

In any of the methods 100, 200 or 800, or systems 300, 600, the waterquality categories may have standards specifying ranges for at least oneof, at least two of, at least three of, at least four of, at least fiveof or at least any other number of or all of the following: TDS,carbonate content, pH, hardness, sodium, chloride, nitrate, toxins andsodium adsorption ratio.

System 600may comprise at least one computer 610 of at least one commoditiesexchange 60S outputting prices of various commodities and in particularvarious commodities that are not water. At least one of thesecommodities may be a root commodity that either has fresh water as aconstituent or whose production utilizes fresh water or both. To takeone simple example of a root commodity, corn may be a root commoditysince it contains water and independently since it utilizes water in itproduction.

Instead of a commodities exchange any other source of updateable currentinformation on commodities prices that is linked to a computer may beused. An example of this is a web site having commodities prices linkedto a server computer.

System 600 may also include a system computer 620 having the hardwareand software elements shown in FIGS. 6A-6B for systems 300 and 300B.

The system computer 620 may be linked(for example by a telecommunications link) with, and may be configuredto receive from, the at least one computer 610 of the at least onecommodities exchange updateable price data for the commodities. Thesystem computer 620 may be configured to identify root commodities andextract, from the updateable price data, the current price for theidentified root commodities. In addition, the system computer 620 and/orprocessor 622 may also configured to or programmed to

-   -   (a) store water quality standards for at least one of or at        least two of (or at least three of etc.) water quality        categories and/or grades,    -   (b) process associations (i.e. determine and/or store        associations) between each of at least one of the water quality        categories (and/or grades) in the at least one (or at least two,        etc.) water quality category with at least one identified root        commodity of the at least one identified root commodities such        that a quality of water used in production (and/or that is        constituent in the identified root commodity) of the identified        root commodity meets (or in some preferred embodiments is        related to) water quality standards of the respective water        quality category.    -   (c) compute, for each water quality category of the at least one        water quality category, a current index value for fresh water        meeting said each water quality category, the current index        value determined based on a current price of said each        identified root commodity associated with said each water        quality category and based on at least one of (i) a quantity of        fresh water constituent in said each identified root commodity        associated with said each water quality category and (ii) a        quantity of fresh water used in production of said each        identified root commodity associated with said each water        quality category. Processor 622 may also be programmed to        compute the current index value by reference to a market share        of respective water sales in respective water quality qualities        (and/or grades) and/or by reference to a market share of various        root commodities.

The system computer 620 may be configured to transmit the computedcurrent index value of each water quality category to the at least onecomputer 610. As shown by the arrows in FIG. 7, this may complete a datacycle that may include a first leg running from the at least onecomputer 610 to the system computer 620 and a return leg or second legrunning from the system computer 620 to the at least one computer 610.The data cycle may involve extracting commodity price data from computer610 and returning prices of water, for example prices based on waterquality, from system computer 620 to the at least one computer 610.

System 600 may also include a water quality measuring device 680 formeasuring fresh water of at least one water source with respect to atleast one of TDS, carbonate content, pH, hardness, sodium, chloride,nitrate, toxins and sodium adsorption ratio to categorize the freshwater of the at least one water source by water quality category and/orto categorize the fresh water of the at least one water source by waterquality grade within a water quality category of the fresh water of theat least one water source. System computer 620 may be configured toreceive data from water quality measuring device 680, or from a computeror other device that stores such data and to compare the received dataagainst stored water quality standards to determine a water qualitycategory and/or water quality grade for the fresh water.

As shown in FIG. 7, system 600 may also include a display 630 (of thekind shown in FIG. 5A for example) associated with the at least onecomputer 610. The “association” may allow feeding and displaying ofupdated current prices in real time. The prices or indices of theindependent variable and of the dependent variable may be updated atintervals of months, weeks, days, hours, minutes, seconds or any otherreasonable interval. The display 330 may have a first portion 331 and asecond display portion 332. Display 330 may display at least one currentindex value for fresh water of a water quality category and/or grade infirst portion 331 of the display which may be updated over time and maydisplay prices of identified root commodities from which the at leastone current index value for fresh water is derived on second portion 332of the display which may be updated over time. In one example shown inFIG. 5A, there are two adjacent and moving areas of the display, such as“ticker tapes”, one showing prices and names of root commodities and oneshowing prices and names of water commodities, i.e. fresh water of aparticular grade or water quality category. A viewer may be able toobserve both portions of display 330 and may be able to observe that asthe prices of the underlying root commodities changes, there is a changein the price of a related or associated water index, i.e. a water indexwhose price is derived from such root commodity as computed by aprocessor using factors, relationships, algorithms, calculations,functions and/or methods described in this patent application.

Alternatively, as shown by the dashed lines in FIG. 7, the display 330may be associated with system computer 620 rather than the at least onecomputer 610 or may be associated with both of them (610, 620).

As exemplified by the arrow in FIG. 8, the results or dataascertained by the device 780 may be transmitted to a computer 710 forstorage and processing. Specifically, computer 710 may be configured toreceive data from the water quality measuring device with respect to thefresh water in regard to the at least one of TDS, carbonate content, pH,hardness, sodium, chloride, nitrate, toxins and sodium adsorption ratioand for comparing the received data to stored water quality standards todetermine a water quality category for the fresh water.

Computer 710 may also be (and may have programming instructions in code)for determining current prices of at least one root commodity that isother than water, each root commodity of the at least one root commodityhaving at least one of (i) water as a constituent in the root commodityand (ii) water utilized in production of the root commodity, forprocessing associations between each of at least one water qualitycategory and at least one root commodity; and for determining a currentindex value for fresh water of each water quality category of the atleast one water quality categories based on a current price of said eachroot commodity and based on at least one of (i) a quantity of freshwater constituent in the root commodity associated with said each waterquality category and (ii) a quantity of fresh water used in productionof the root commodity.

In some embodiments of system 700, computer 710 may also be fordetermining a water quality grade, and for processing associationsbetween each of at least one water quality grade with the at least oneroot commodity; and determining a current index value for fresh water ofeach water quality grade based on a current price of said each rootcommodity and based on at least one of (i) a quantity of fresh waterconstituent in the root commodity associated with said each waterquality grade and (ii) a quantity of fresh water used in production ofthe root commodity. System 700 may also include a display 730 associatedwith computer 710, for example a display 730 similar to the displayshown in FIG. 5A or FIG. 5B, and may have the features described inrelation to the display of the previously described methods and/orsystems of the present invention. For example, display 730 may displayboth an independent variable (i.e. updateable current prices of at leastone root commodity) and a dependent variable (updateable current pricesof fresh water of a particular water quality category and/or waterquality grade. The fresh water whose price may comprise the dependentvariable may be a constituent of and/or may be utilized in theproduction of at least one of the root commodities whose price maycomprise the independent variable or variables.

In any of the systems or methods of the present invention, a computerprocessor may use one or more mathematical operations to mathematicallycombine factors such as a quantity of fresh water constituent in a rootcommodity, a quality of fresh water utilized in production of a rootcommodity, a price of a root commodity, a market share (market weight)of fresh water of a particular water quality category and/or gradewithin a total market of fresh water, a suitability factor, a base priceof water, an adjustment factor, a market share of one or more particularroot commodities out of a total market of all relevant root commodities,a quantity of fresh water in a particular collateral, a quantity offresh water described on the face of a financial instrument or otherfactors. Any of these factors may be updated regularly at reasonableintervals as necessary and if possible and appropriate in real time.Prices of root commodities, for example, may be updated in real timefrom a commodities exchange (see 608 in FIG. 7). Data for determiningmarket shares and prices of products may come from publicly availablestatistics, for example information available over the Internet (forexample statistics may be acquired from web sites associated withcommodities markets, futures markets, stock exchanges (for example atN.Y., Chicago, London, Tokyo) and therefore can be updated easily inreal time. Alternatively, statistics may be updated from periodicallyfrom published statistics or from statistics released from a governmentagency.

Any of the commodities referred to herein may be publicly tradedcommodities.

As seen from FIG. 4, the present invention may be described as a method400 for investing in fresh water based on a quality of the fresh water.Method 400 may comprise a step 410 of determining, using a computerprocessor, current prices of one or more (or of two or more or three ormore, etc.) root commodities, the root commodities being other thanwater, each root commodity in the at least one or (or at least two etc)root commodities having at least one of (i) water as a constituent insaid each root commodity and (ii) water utilized in production of saideach root commodity. Step 420 may involve matching each of at least onewater quality category and/or water quality grade in the at least onewater quality category and/or grade with at least one root commodity ofthe at least one (or at least two, etc) root commodity. Step 430 maycomprise determining, using a computer processor, for each water qualitycategory (and/or grade) of the at least one water quality category, acurrent index value for fresh water meeting said each water qualitycategory, the index value determined based on a current price of saideach root commodity that was matched with said each water qualitycategory and based on at least one of (i) a quantity of fresh waterconstituent in said each root commodity that was matched with said eachwater quality category and (ii) a quantity of fresh water used inproduction of said each root commodity that was matched with said eachwater quality category.
